Mechanics

Mechanics is a branch of physics. Mechanics examines the phenomena of motion. Mechanics could be divided into two branches:
• mechanics of non-deformable bodies
• mechanics of deformable bodies
Mechanics examines and describes rules of motion. On this page examples are about classical mechanics. Classical mechanics is applied when examined objects are big and when their velocities are small in relation to speed of light in vacuum. If mentioned conditions are fulfilled then results obtained via classical mechanics theory are true with experiment results. To describe phenomenas of motion for very small objects which are comparable with atoms or elementary particles we have to use quantum mechanics. For objects which are moving with velocities close in relation to speed of light, we have to apply relativistic mechanics which is described by Einstein’s special theory of relativity. You can find here a lot examples from mechanical engineering and strength of materials. Every example is solved step by step.
